Abstract

Discharge printing of cotton fabrics with sodium- and zinc formaldehyde sulphoxylate with different fixation conditions was discussed
in this study. Superheated steam, saturated steam and thermofixation were used for fixation processes. It was observed that steam based
fixations resulted in the higher discharging effects, while thermofixation lead to an inadequate effect even in higher temperatures.
Superheated steam was found to be advantageous in terms of lower fixation times. Sodium formaldehyde sulphoxylate gave superior
discharging effects compared with zinc formaldehyde sulphoxylate, which caused higher strength loss especially in superheated steam
fixation. Furthermore, the effects of the softeners on the discharge printing results were also investigated in the scope of the study.

Keywords

Discharge printing, Fixation, Strength loss, Softeners.
